Description
The IceCube detector has observed the first clear detection of a diffuse astrophysical high energy neutrino flux, however, the sources for these neutrinos have yet to be found. Hadronic interactions around cosmic ray accelerators result in both high energy gamma and neutrino fluxes for neutral and charged pion decays respectively. Observing cosmic ray sources with neutrinos provides unique evidence of the hadronic nature of these sources. Recently there have been many analyses from IceCube using multiple years of data for the detector in order to establish a neutrino source. These searches involve looking for a significant clustering of neutrinos from any direction or a strong correlation with a known source observed by other messengers also expected to emit a neutrino flux. These searches range from stacking searches involving populations of similar sources such as active galactic nuclei, to time-dependent searches targeting individual sources when they are in flaring states. We present here the most recent updates in the search for sources of extraterrestrial neutrinos using the latest methods and source information.
